Question

Me ayudarian a resolver etsa operaciones por favor

Answer 1

2.
$\frac{ \times + 1}{2x} + \frac{2x + 3}{3x} = \\ mcm = 3x \\ x(x + 1) + 2x + 3 = \\ {x}^{2} + x + 2x + 3 = \\ {x}^{2} + 3x + 3$
4.
$\frac{2x + 5}{6x} - \frac{x + 6}{4 {x}^{2} } = \\ mcm = 4 {x}^{2} \\ 2x(2x + 5) - (x + 6) = \\ 4 {x}^{2} + 10x - x - 6 = \\ 4 {x}^{2} + 9x - 6$
